Semiconductor element

Abstract

A semiconductor element includes a first coil substantially located at a first plane; a second coil substantially located at the first plane; a connecting section that connects the first coil and the second coil; a third coil substantially located at a second plane different from the first plane; and a fourth coil substantially located at the second plane. The third coil and the first coil are connected through a through structure, and the fourth coil and the second coil are connected through a through structure. The third coil and the fourth are not directly connected.

What is claimed is: 
     
       1. A semiconductor element, comprising:
 a first coil, substantially located at a first plane; 
 a second coil, substantially located at said first plane; 
 a connecting section, connecting said first coil and said second coil; 
 a third coil, substantially located at a second plane different from said first plane; and 
 a fourth coil, substantially located at said second plane; 
 wherein, said third coil and said first coil are connected through a through structure, said fourth coil and said second coil are connected through a through structure, and said third coil and said fourth coil are not directly connected. 
 
     
     
       2. The semiconductor element of  claim 1 , wherein metal segments of said third coil substantially overlap metal segments of said first coil, and metal segments of said fourth coil substantially overlap metal segments of said second coil. 
     
     
       3. The semiconductor element of  claim 1  further comprising:
 a guide segment section, connected to said third coil and comprising a first guide segment and a second guide segment; 
 wherein said guide segment section partially overlaps regions surrounded by said first coil and said third coil. 
 
     
     
       4. The semiconductor element of  claim 1  further comprising:
 a center tap, connected to said fourth coil; 
 wherein said center tap partially overlaps regions surrounded by said second coil and said fourth coil. 
 
     
     
       5. The semiconductor element of  claim 1  further comprising:
 a first end, located at said third coil; 
 a second end, located at said third coil; and 
 a center tap, connected to said fourth coil; 
 wherein, said semiconductor element is an integrated inductor, said first end and said second end are two ends of said integrated inductor, and said center tap is a center of said integrated inductor. 
 
     
     
       6. The semiconductor element of  claim 1  further comprising:
 a first end, located at said third coil; 
 a second end, located at said third coil; 
 a third end, located at said fourth coil; and 
 a fourth end, located at said fourth coil; 
 wherein, said semiconductor element is an integrated transformer that uses said first end and said second end as one of an input port and an output port of said integrated transformer, and uses said third end and said fourth end as the other of said input port and said output port.
